Try hooking the target disk as the default drive (0x80) and using --drive 0x81 
for win2k8.iso, i.e.:

  sanhook iscsi:
  sanboot --no-describe --drive 0x81 http://ip/win2k8.iso

[ By the way, there's no need to use "set keep-san 1" when you're SAN-booting 
the ISO directly; "keep-san" is only needed if you're going to exit out of 
iPXE back to the BIOS in order to boot from a physical CD. ]
